The reaction of cyclohexanone with dimethylamine in the presence of a catalytic amount of an acid forms a compound if water is continuously removed during the reaction. The compound formed is generally known as:

The reaction of methylamine with acetyl chloride is similar to the reaction of aniline with . . . . . . .

Explain: Acetylation.

In the reaction: $\text{Primary Amine} + CHCl_3 + KOH \rightarrow \text{Product}$,what is the product?

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: Experimental reaction of $CH_{3}Cl$ with aniline and anhydrous $AlCl_{3}$ does not give $o-$ and $p-$methylaniline.
Reason $(R)$: The $-NH_{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $AlCl_{3}$ and hence yields $m-$methylaniline as the product.
In the light of the above statements,choose the most appropriate answer from the options given below.

The major product in the above reaction is:
